Over the past three decades, it has been recognized that bycatch and discard is one of
the most significant issues effecting fisheries management (Saila, 1983; Alverson et al.,
1994). In this study, bycatch and discarded crab pot catches in different fishing area (inshore,
offshore) in the Upper Gulf of Thailand were considered using data obtained from joining
the operation with the crab pot fishermen for a consecutive year. As the information on the
discarding procedure in the area were very limited, the main features of this process was
presented, the quantities and qualities of discarded species were reported. Moreover, the
CPUE according to the soaking time with the different retrieval method of commercial scale
pot was examined.
